Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489558, here are decompositions:

157 + 2147489401 = 2147489558
211 + 2147489347 = 2147489558
499 + 2147489059 = 2147489558
541 + 2147489017 = 2147489558
691 + 2147488867 = 2147489558
1129 + 2147488429 = 2147489558
1279 + 2147488279 = 2147489558
1447 + 2147488111 = 2147489558

Showing the first eight; more decompositions exist.
